Smell of gas fumes underneath vehicle near fuel tank
I have a 2004 Volvo XC-90. I have been smelling gas fumes outside the vehicle. Gas cap seems to be fine but after looking underneath, the smell of fumes are stronger near the gas tank. Don't see any leaks. I do see a gas stain. Could this be a cracked hose or something. Appreciate any and all suggestions. Thanks, Gregg Primus
Re: Smell of gas fumes underneath vehicle near fuel tank
I also have a 2004 XC90 and a couple of months ago I had the exact same probelm... after multiple visits to my dealer's auto shop they figured out that it was the fuel pump. They replaced the fule pump and the smell disappeared. Good luck!

Do not top off your gas tank. The gas is going into carbon canister which is only for fuel vapors to go into (carbon canister opening near the top of fuel neck near the gas cap). Your flooding the fuel vapor canister with liquid fuel; of course you are going to get a sensor message...
'Evap emmission,control sys leak
P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned again...it's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)
I had a similar problem with a 2000 Kia Sportage. The check engine light came on all the time. Part of the problem seemed to be the fuel cap having high pressure. Then one fine day I smelled gas fumes from the rear of the vehicle. After removing the fuel pump cover in the rear behind the seats, I found gas coming from a hose from the tank. I then (sometime later) I found a crack in another hose. The hose was from the filler neck. It caused a lack of vapor pressure and a smell. The check engine light now was off.
Fuel tanks have a vent tube and a charcoal cannister to capture the gas fumes from the tank. It's possible there is a cracked or loose hose, faulty fuel cap, bad canister or a fuel leak and any one of many connections. Investigate for sign of raw fuel along the underside of te vehicle, and in the engine compartment. Attempt to follow the smell to isolate the location of a leak.
is your purge canister working correctly or does it cause the fumes to stay in fuel tank and smell from the tank cap. Check when the car is off by removing the filler cap whether you have a pressure in tank. this might cause the smell,unless there is a small leak not noticeable somewhere.
normally fumes come in to vehicle when stopped because of oil leak from rocker cover but check your fuel filler cap seal etc and also incase the tank is leaking just have a sniff at the rear of the car if its the filler cap or tank filler you normally get smell when tank is nearly full and been around a few corners the fuell filler nect becomes pourous and just spills out a bit if so will need replacing .but most time its an oil leak from rocker box or engine
